Hi Naoto,

Thank you for the response. You are correct. I ran the reproducer against JDK13 
and JDK9, and they appear not to differentiate between L and M as long as the 
input is consistent. I will update the bug and revise the effort accordingly. 
Thanks!!

for month-of-year

Hi Thejasvi,

M/L does not designate textual nor numeric. Thus I don't think that the 
suggested documentation fix is correct. Furthermore, although the exception in 
JDK8 looks like a bug, the test result with JDK9 looks correct to me. The month 
displayed as "04" is the result of
ZonedDateTime.toString() so should not be localized.
